Coherence-Mediated Quantum Thermometry in a Hybrid Circuit-QED Architecture
Shaojiang Zhu, Xinyuan You, Alexander Romanenko +1
Quantum thermometry plays a critical role in the development of low-temperature sensors and quantum information platforms. In this work, we propose and theoretically analyze a hybr…
Analysis of RF Surface Loss in a Planar 2D Qubit
Andrei Lunin, Mustafa Bal, Akshay Murthy +3
The Josephson junction and shunt capacitor form a transmon qubit, which is the cornerstone of modern quantum computing platforms. For reliable quantum computing, it is important ho…
Squeezing enhanced sensing at an exceptional point
Changqing Wang, Deyuan Hu, Silvia Zorzetti +3
Pushing the boundaries of measurement precision is central for sensing and metrology, pursued by nonclassical resources such as squeezing, and non-Hermitian degeneracies with disti…
Demonstrating magnetic field robustness and reducing temporal T1 noise in transmon qubits through magnetic field engineering
Bektur Abdisatarov, Tanay Roy, Daniel Bafia +10
The coherence of superconducting transmon qubits is often disrupted by fluctuations in the energy relaxation time (T1), limiting their performance for quantum computing. While back…
Ultracoherent superconducting cavity-based multiqudit platform with error-resilient control
Taeyoon Kim, Tanay Roy, Xinyuan You +26
Realizing the promise of quantum computing requires simultaneously increasing Hilbert-space size and coherence times. While qubit-based architectures have long been the dominant pa…
Floquet-engineered fast SNAP gates in weakly coupled circuit-QED systems
Xinyuan You, Andy C. Y. Li, Tanay Roy +5
Superconducting cavities with high quality factors, coupled to a fixed-frequency transmon, provide a state-of-the-art platform for quantum information storage and manipulation. The…
